The number counters on the top of the ideas spaces in Microsoft Tech Community give the number of ideas related to the status of the idea (New, On Hold, Closed, etc.). What I see is when we select a label, we see the posts with that label but the counters on the top give numbers of the whole space. My suggestion is to update the number counters when a label selected meaning to show only the status number of ideas related to the label and not of the whole space when a label is selected.
The number counter on the top of Ideas Space shows number of ideas according to their status.
Suggestion: When a label is selected, the number counter should only show number of ideas according to the status with that label.
